Thanks.  Please report back.

I'm about to announce a new test release that tries to work around the problem 
in a different way.  I'd be interested in hearing how that works too.

Yes.  Each build environment for emacs requires its own compiled libraries. 
Here "build environment" includes source files, system, and configuration 
options.  In this case, the build of emacs-w32 used the configuration option 
"--with-w32" that wasn't used in the build of emacs-X11.

Thanks very much for testing!
